function x = ldlsolve (LD,b) %#ok
%LDLSOLVE solve LDL'x=b using a sparse LDL' factorization
%
% Example:
% x = ldlsolve (LD,b)
%
% solves the system L*D*L'*x=b for x. This is equivalent to
%
% [L,D] = ldlsplit (LD) ;
% x = L' \ (D \ (L \ b)) ;
%
% LD is from ldlchol, or as updated by ldlupdate or ldlrowmod. You must not
% modify LD as obtained from ldlchol, ldlupdate, or ldlrowmod prior to passing
% it to this function. See ldlupdate for more details.
